To all whom it may concern.

Be it known that I, JACOB H. HARRIsoN, a citizen of the United States, residing at Falls City,in the county of Richardson and State of Nebraska, have invented a new and useful Improvement in Combined Mops and lVringei-s, of which the following is a specification. I

This invention relates to combined mops and wringers, and is an improvement on the structure shown, described and claimed in Patent No. 1,142,628, issued to Roy A. Rodgers and myself on June ,8, 1915, on a combined mop and wringer.

One object is to improve the structure by the elimination of some of, the fastening bolts and screws formerly used, and forming the cross piece constituting the mop head in one piece carried by a' stout ferrule for the mop handle, which lends great strength and durability to the mop and wringer. v

Another object is'to improve theconstruction of-the tension springs for forcing the compression rollers together by'rigidly securing the springs to the metallic mop head instead of to the wooden mop handle, and by the provision of set screws for adjusting the tension of said springs to properly accommodate the cloth between the rollers, the cloth being adapted to be carried on the mop head at all times until wornout, and readily removable therefrom for the purpose of renewal by simply adjusting the said screws to permit the co-acting rollers to separate sufficiently for the passage of the terminal wire loops carried by the cloth.

A final object is to provide co-acting compression rollers which will extract the maximum amount of water from the mop cloth, as the latter is drawn therebetween, especially along themargins of said cloth, the stationary roller in the present construction being provided with two equal, opposed frusto-conical portions, the smaller diameters of which form the point of juncture at the longitudinal center ofthe roller.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification; it being understood that while the drawing shows a practical form of the in vention, the latter is not to be confined to strict conformity with the showing thereof,

but maybe changed or modified, so long as I tion and with the mop cloth removed;

Figure 3 is a side elevation of the complete device; v

F igure d is a detail perspective view of the mop head and tension springs, with the handle and compression rollers removed.

The main frame or mop head of the improved mop. and wringer comprises a continuous cross bar 1 formed of stout bar metal preferably of flat form and terminating at each end in a downwardly extending side arm 2, formed integrally therewith and providing the maximum amount of strength to withstand the rough usage to which mops are subjected.

To the upper or outer face of the cross bar 1,a'nd at the longitudinal center thereof, there is secured an upstanding ferrule 3 having its lower, abutting end closed by a wall 1, and adapted to receive in its outer,

open end, the reduced shank 5 of an ordinary operating handle 6. The wall 4 of the ferrule, as well as-the bar 1, are suitably apertured for the reception of a fastening rivet 7, which may be of any desired form to rigidly fasten the ferrule in place on the mop head. The ferrule 3 and the reduced shank 5 of the handle are also suitably apertured for the reception of a cross pin 8 which securely holds the handle to the ferrule.

The'lower, free ends of the side arms are provided with open-ended slots '9 in which are adapted-to slide the trunnions 10 of a spring-pressed roller 11, the ends of which are adjacent to the inner facesof the side arms 3 and free to revolve between the same. The roller ll'has parallel sides or walls, and the trunnions 10 are extended beyond the arms 2 and are provided with heads 12, and mounted on each trunnion, between the arms 2 and the heads 12, are the lower apertured ends 13 of L-shaped springs 14, the upper arms of which are bowed downwardly and provided with terminal, attaching portions 15, adapted to rest upon the upper face of the cross bar 1 adjacent to the ferrule, the said attaching portions and cross bar being suitably apertured for the reception of rivets 16, which securely hold the springs to the mop head and permit of more or less resiliency in the said springs having the roller 11 mounted in the lower ends thereof.

Adjustable set screws or thumb screws 17 are passed through suitable threaded apertures in the cross bar 1, substantially midway between the rivets 1.6 and'the side arms 2, and the free ends of the screws bear against the under sides ofthe springs 14 to normally elevate the roller 11 or lower the same in theslots 9.

Journaled inthe side armsQ between the roller 11 and the cross arm 1, is asecond compression roller 18 having'end trunnions mounted in suitable bearing openings formed in the side arms, so that the said roller is held in fixed position, parallel to and spaced from the spring pressed roller 11. The static-nary. roller 18 is formed slightly converging; from each end to the center thereof soithat the same is in effect like: two opposed frusto-conical portions joined at their smaller endspand this proision isamade for increased passageway at the centerof the mop. to: allow for the passage-of the greatest bull: of the mop cloth at the center and to insure the thorough wringing f the longitudinal margins of said cloth. The mop cloth 19 consists of an elongated strip of suitable material of a width to freely pass between the side arms 20f the mop heads As shown in Figure 3 of the drawing, the mop cloth is provided at each end with: a hem 20, through each of whiclris passed the main-bar'21 of a wire frame- 22, the sides 28 of which converge outwardly and are then directed inwardly towards each other, as at 24:, and terminate in an upstanding 100 325, having parallel sides adaptedto rest longitudinally against and to-beheld' to the handle 6 by'spaced screws or otherheaded projections 26, which rigidly holdeach of the wire frames at each endof the" clothto-the handle. By drawing the cloth through between the rollers suiii ciently, the loop 25 may he slid into engagement with the headedscrews or projections 26 andthe slaclr in the cloth taken up so that the-bulk of the same will'be to one side of'the mophead, as clearly shown in Figure 3, when the'mop is applied to the floor and manipulated in the usual manner/ Either oneof the wire framesmay be readily detached from the projections and the cloth pulled through the passageway between the rollers, when the pressure of the springs upon the lower roller will extract the water therefrom, after which the loose end of the cloth is attached again and the mopping operation proceeded with.

From the foregoing it will be seen that important changes and substantial improvements have been made over the structure of the aforesaid patent and incorporated in the present invention, the provision of the meansin the stationaryroller 18 for insuring the uniform wringing of the margins of the cloth, as well as the middle andbulky portions thereof, being especially valuable, as well as the tensioning means for the springs in the form of the adjustable screws 17, thus enabling the use of cloths of greater or less thickness and bulkiness andof increasing or decreasing the pressure between therollers.

hat is claimed-is:

1. A mop and wringer comprising a handle, a transverse bar attached to the handle and having terminal, arms provided ith longitudinal slots in their. terminals, a roller having trunnions mounted to slide in said slots, opposite znigular leaf-springs secured to the said transverse bar and having their free ends engaging the trunnions to force the same intot-he slots, setv screws mounted in the bar to bear against the under sides of said. springs to adjust: the tension of: the same, and a stationary roller mounted between the arms above the first roller and adapted to co-acttherewith towri'ng a mop cloth.

2. A mop and wringer comprising a handle having a ferrule at one end, a trans verse mop headcarriedi by thev ferrule and provided with spaced arms having openended slots in. their terminals, a transverse roller mounted between said arms above said slots, a second-rollermounted to slide in the slots, L-shaped springs each having an arm termin allyssecured to the mop head and pivotally connected to'the secondroller at their otherendsto normally force the same against the first named. roller: to wring. a mop cloth, and set' screws mounted in the mop head and bearing beneath the. secured portions ofthe springsto vary the tension between the'rollers.

In testimony, that I claim the foregoing as my own, I: have hereto aifixed my signature;

JACOB l H. HARRISON.
